NHTSA ID Number: 10114592
Manufacturer Communication Number: PIP5203C
Summary
This Preliminary Information communication provides information to the technician about a service engine soon light on. Technician will find diagnostic trouble codes P0089 and P228D set in the engine control module. This concern could be due to an incorrect intake camshaft or camshaft actuator sprocket. A diagnostic trouble code of P0171 could also set from installing incorrect injectors.

Condition/Concern
Some technicians may comment of a service engine soon light on, low engine power or rough idle after engine, intake camshaft or intake camshaft actuator replacement. Typically, they will find DTC’s P0089 and P228D set in the ECM. The high side fuel pressure at idle will likely be high, around 2000-2500 PSI. They may also note a whine type noise from the high pressure fuel pump. These symptoms occur if the intake camshaft with actuator sprocket are not the correct parts for the vehicle build. A P0171 is also possible if the incorrect injectors were
installed.
Recommendation/Instructions
If the symptoms above are noted after engine, intake camshaft or intake camshaft actuator replacment. It is likely the incorrect parts have been installed. This can be confirmed by removing the camshaft cover and noting the CMP actuator sprocket colors or part number on the actuator sprockets.
A 2010 engine has a black exhaust actuator sprocket and a gray intake actuator sprocket. Each camshaft actuator sprocket will have a different part number. A 2011 engine has black camshaft actuator sprockets for both the intake and exhaust camshafts. Both camshaft actuator sprockets will have the same part number.
Below is an example of a 2011 Chevrolet Equinox intake camshaft actuator part number 12621505 and black in color (plastic cover piece).
The camshafts can be identified by the last four digits of the part number located on a machined surface between the number 2 and number 3 cylinder camshaft lobes.
Below is an example of a 2011 Chevrolet Equinox intake camshaft part number 12634207.
Before a 2010 service engine was available, technicians were directed to install a 2011 service engine into a 2010 vehicle. It was necessary to swap parts from the old engine to the new engine to make it a 2010 build. These parts included the intake camshaft and actuator sprocket, and the fuel rail assembly with injectors. If these parts from the original engine were damaged, new parts designed for a 2010 vehicle were installed. When the intake camshaft and actuator sprocket are swapped, dealers should reference timing procedures for a 2010 model year vehicle. This is important because the intake actuator locating notch in the camshaft moves from about the 10:00 starting position on a 2011 engine to about the 5:00 starting position on a 2010 engine.
The fuel injectors have the part numbers on the injector body. When swapping the fuel rail, if the injectors are not removed from the rail, the retaining clips do not have to be replaced. The Teflon seals at the injector tips however, must be replaced whenever the injectors are reinstalled onto an engine.
The fuel pipe from the high pressure pump to the fuel rail must also be replaced whenever it is removed.
Warranty Information
There is not a labor time or labor operation associated with this PI because the labor time is considered part of the original repair.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

2013 Captiva 2.4 (Same engine and system as Regal)
I did an inframe rebuild (excessive oil consumption and timing chain guide broke).
12,000 out of warranty.
Now I have a random misfire when thoroughly warm, at idle, in gear (P0300)
I got a P228D one time then it went away… The fuel pressure fluctuates wildly, the TPS reading fluctuates, timing goes retard by 30 degrees…
I also had a broken phaser on the exhaust cam (P0014)
But it won’t set a code…
I would start with doing a Crank Sensor Relearn…
I have a Buick Regal 2011 with Engine equinox 2015, I don’t know what is the problem the screen show me a message (Reduced Engine & stailbreak system) The code in the scan are P228D ( Sensor Fuel Pressure Regulator is Exceeded Control limits – Pressure too high) & P0089 (Fuel Pressure Regulator 1 Performance) I have Changed the Pump for Gas, Fuel injection fuel rail pressure sensor (GM-12635273), Fuel injection throttle body with throttle actuator (AC-delco 217-3428), High Pressure Fuel pump with seal,retainer,gasket,and bolt (ACdelco EP1028), Mass Air FLow sensor (15865791 OEM 167A), Mainfold Absulute Pressure Sensor (ISUMO 12591290) & 2 PCS OK 1516V Variable timing Solenoid Intake & exhaust camshaft Position actuator oil control Valve 4 Cyliner Engine 2.0 L 2.4L VVT OCV.
Always the problem is here.
you may have a wiring issue, you need to have it properly diagnosed.
I have the same problem when I swapped my 2010 terrain with a 2012 Engine. P228D and P0089 with reduce engine power. I was told the Camshaft and phaser was different shaped them now it runs worse.
Hi Hello I have a chevrolet equinox 2010 and the engine broke, buy a 2013 and I’m giving problems with high pressure of gas, it can be solved or there is q change the engine?
I don’t know, I would check with the dealer if 2013 is different from 2010.
I have a 2010 gmc terrain, my engine makes a wining sound when accelerating..what could it be?
It could be anything, a bad bearing, low power steering fluid. I would take it to a shop, and see if they can pin point where the noise is coming from.
